What type of quikcrete product?

I live in philadelphia in a twin house. Upper half of home is brick and lower half is stone with concrete outline(Some sort of concrete with pebbles in it. I have some concrete falling off and unsure what type of quickrete product to purchase. I was thinking about using the hydraulic patch. I like the texture and color. Should I use the quick setting cement. I'm buying the stuff in a bucket. Or is there a special kind of product for masonary/exterior that will blend into the existing concrete?
